A Decade-Long Increasing Mid-Infrared Luminosity in Galaxy NGC6447: a Turning-On Candidate of Active Galactic Nucleus
Xinyu Dai, Nate Adams, Natalie Kovacevic +6
It is widely expected that the obscured accretion stage can be the initial turning-on stage of active galactic nuclei from quiescent galaxies. We present mid-infrared light curves…
The assembly of supermassive black holes at in early-type galaxies from scaling relations
Duncan Farrah, Athena Engholm, Evanthia Hatziminaoglou +14
The assembly of supermassive black hole (SMBH) mass () and stellar mass () in galaxies can be studied via the redshift evolution of the rela…
Massive black holes in galactic nuclei: Theory and Simulations
Tiziana Di Matteo, Daniel Angles-Alcazar, Francesco Shankar
Massive black holes are fundamental constituents of our cosmos, from the Big Bang to today. Understanding their formation from cosmic dawn, their growth, and the emergence of the f…
The low-end of the black hole mass function at cosmic dawn
Alessandro Trinca, Raffaella Schneider, Rosa Valiante +3
Understanding the formation and growth of supermassive black holes (SMBHs) at high redshift represents a major challenge for theoretical models. In this work we investigate the ear…
Supermassive Black Holes and Their Host Galaxies - II. The correlation with near-infrared luminosity revisited
Ronald Läsker, Laura Ferrarese, Glenn van de Ven +1
We present an investigation of the scaling relations between Supermassive Black Hole (SMBH) masses (Mbh), and their host galaxies' K-band bulge (Lbul) and total (Ltot) luminosities…
Black Hole Demography: From scaling relations to models
Francesco Shankar
In this contributed paper I review our current knowledge of the local Black Hole (BH) scaling relations, and their impact on the determination of the local BH mass function. I part…
Accretion-Driven Evolution of Black Holes: Eddington Ratios, Duty Cycles, and Active Galaxy Fractions
Francesco Shankar, David H. Weinberg, Jordi Miralda-Escude'
We develop semi-empirical models of the supermassive black hole and active galactic nucleus (AGN) populations, which incorporate the black hole growth implied by the observed AGN l…
The Demography of Super-Massive Black Holes: Growing Monsters at the Heart of Galaxies
Francesco Shankar
Supermassive black holes (BHs) appear to be ubiquitous at the center of all galaxies which have been observed at high enough sensitivities and resolution with the Hubble Space Tele…
On the radiative efficiencies, Eddington ratios, and duty cycles of luminous high-redshift quasars
Francesco Shankar, Martin Crocce, Jordi Miralda-Escude' +2
We investigate the characteristic radiative efficiency ε, Eddington ratio λ, and duty cycle P_0 of high-redshift active galactic nuclei (AGN), drawing on measurements of the AGN lu…
Self-Consistent Models of the AGN and Black Hole Populations: Duty Cycles, Accretion Rates, and the Mean Radiative Efficiency
Francesco Shankar, David H. Weinberg, Jordi Miralda-Escude'
We construct evolutionary models of the populations of AGN and supermassive black holes, in which the black hole mass function grows at the rate implied by the observed luminosity…
Super-massive Black Hole Demography: the Match between the Local and Accreted Mass Functions
F. Shankar, P. Salucci, G. L. Granato +2
We have performed a detailed analysis of the local super-massive black-hole (SMBH) mass function based on both kinematic and photometric data and derived an accurate analytical fit…
